Following the bit-level floating-point coding rules, implement the function with the following prototype:

For floating-point number f , this function computes (int) f . Your function should round toward zero. If f cannot be represented as an integer (e.g., it is out of range, or it is NaN), then the function should return 0x80000000.

Test your function by evaluating it for all 2³² values of argument f and comparing

the result to what would be obtained using your machine’s floating-point

operations.
